I'm working with my mechanic on this one, but since he doesn't have a smoke
machine, I'm trying to narrow down potential problem points.

Noticed it was running rough a while back, initially thought it was a
timing/misfire issue.
New plugs, cap, rotor, ignition wires all needed to happen anyway, but
didn't have an impact.

A couple interesting points:
- Noticing a sucking sound coming from the general area of the airflow
sensor.
- It runs rough every time I start up, but eventually smoothes out after
idling for a few minutes.
- The sucking/whistling sound seems to be related because it subsides
(mostly) concurrent to the idle smoothing out.

At first I thought it might be an intake hose crack, and that increased
temp would cause a temporary expansion / seal, but that doesn't seem to be
it since it happens on every startup, even after everything is warm.

Anyone else experienced this before?
Any tips on where to look?
